Abstract
The utility model relates to a boiler burning edible fungus dregs, which comprises a boiler main body, a feeding system, a combustion chamber, smoke and an air flue; an air preheater is mounted on the thick surface of the boiler, an anti-bridging bunker is mounted in the front thereof, a screw feeder is mounted below the anti-bridging bunker, an inclined boiler wall is arranged at the front end of the combustion chamber behind the screw feeder, an alternative air supply channel is arranged on the inclined boiler wall, the pipeline of the air preheater is communicated with the alternative air supply channel, and the combustion chamber adopts a thermal insulation combustion chamber without heating surface. By the adoption of the utility model, the high-moisture edible fungus dregs can be ensured to burn stably without being dried outside the boiler, thereby saving the investment of the drying equipment and realizing the short-distance connection between the boiler and the edible fungus production line because the outside furnace drying process..
Description
Affiliated field
The utility model relates to a kind of boiler, relates in particular to a kind of boiler of the food bacterium slag that burns.
Background technology
The moisture 40～50% of food bacterium slag, utmost point difficult to burn, former combustion technology requires earlier to the oven dry of food bacterium slag, send into turbulent burner and combustion chambers burn with blower fan and conveyance conduit again, the complex process investment is big, troublesome poeration, floor space is big, very easily causes fire with flue gas drying in dryer.
Summary of the invention
The utility model main purpose is to overcome the deficiencies in the prior art, thereby it is simple to develop a kind of technology, easy to operate combustion food bacterium slag boiler.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of combustion food bacterium slag boiler, has boiler body, feeding system, burner hearth, cigarette, air channel, it is characterized in that: air preheater is equipped with in the back of boiler body, anti-bridging feed bin is equipped with in the front, below the anti-bridging feed bin screw(-type) feeder is arranged, burner hearth front end behind screw(-type) feeder has pre-heating drier, be furnished with the alternation air-supply passage above the pre-heating drier, the pipeline of described air preheater is connected with the alternation air-supply passage.
The technical solution of the utility model can also be further perfect:
As preferably, described pre-heating drier is the inclination furnace wall that is arranged on the burner hearth front end.
As preferably, described burner hearth is the adiabatic furnace of no heating surface.
Described food bacterium slag hearth feeding system adopts spiral to advance continuously, realizes continuously feed equably by screw(-type) feeder.
Burner hearth front end behind the screw(-type) feeder is arranged an inclination furnace wall, and fuel obtains separating out of preheating, oven dry and part fugitive constituent herein.
On the inclination furnace wall, arrange the air channel, fuel is sowed by the alternation wind in the air channel; Fuel is evenly distributed on fire grate.
Burner hearth is an adiabatic furnace, no heating surface.
The chamber of employing combustion simultaneously, two kinds of combustion technologies of grate firing; Fuel is sowed at the burner hearth inner drying through wind-force and is caught fire, and falls the fuel stratiform after-flame on the fire grate.
Primary and secondary air all adopts hot blast, by air preheater air is carried out preheating.
The beneficial effects of the utility model are: present technique adopts that spiral advances continuously, furnace front preheating, alternation wind-force are sowed, the aerial drying of large space is caught fire, on the fire grate stratiform burn, know-how measures such as the adiabatic short combustion of burner hearth, air preheat, the food bacterium slag of guaranteeing high-moisture can smooth combustion without the outer oven dry of stove; Because saved the outer drying course of stove, the associative operation personnel have also been saved in the investment of having saved drying plant, have reduced floor space, realized closely being connected of boiler and Edible Fungi line.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Description of reference numerals: the 1-screw(-type) feeder, 2-inclination burner hearth, 3-alternation air channel, the 4-adiabatic furnace, the 5-fire grate, the 6-air preheater, 7-prevents the bridging feed bin.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
Combustion food bacterium slag boiler is as shown in Figure 1 formed food bacterium slag hearth structure by boiler body, feeding system, burner hearth, cigarette air channel, air preheater.Fuel is entered the screw(-type) feeder 1 of stokehold by anti-bridging feed bin 7, fuel is evenly sent into burner hearth 4 continuously, be deposited on the inclination furnace wall 2 of burner hearth front end, the fuel that the fuel that constantly enters afterwards promotes on the furnace wall travels forward, and the high-temperature flue gas in this process in the burner hearth 4 has carried out preheating to fuel.Fuel is blown by the heat primary air in alternation air channel 3, sows in burner hearth 4, owing to adopt alternation wind, fuel is sowed in furnace cavity equably.The further aloft drying of fuel is caught fire, and fugitive constituent is separated out burning in the air at burner hearth, i.e. chamber combustion does not burn the fuel of falling on the fire grate and continues to burn on fire grate 5, be i.e. grate firing.Do not have heating surface in the burner hearth 4, belong to adiabatic furnace, a secondary wind is all through air preheater 6 preheatings, and these measures can improve the ignition temperature of fuel in burner hearth 4, accelerates the after-flame of fuel.Chimney arch with 90% coverage rate separates fuel combustion chamber and top heat transfer burner hearth.Form burning and separate with two thermal processions of conducting heat, (combustion zone temperature can reach 900～1100 ℃, reaches the stable purpose that uses than the edible fungi residues of high-moisture in the hope of improving the fuel combustion zone temperature.
Claims (3)
1. bacterium slag boiler is eaten in a combustion, has boiler body, feeding system, burner hearth, cigarette, air channel, it is characterized in that: air preheater is equipped with in the back of boiler body, anti-bridging feed bin is equipped with in another front, prevents below the bridging feed bin screw(-type) feeder being arranged, and the burner hearth front end behind screw(-type) feeder has pre-heating drier, be furnished with the alternation air-supply passage above the pre-heating drier, the pipeline of described air preheater is connected with the alternation air-supply passage.
2. combustion food bacterium slag boiler according to claim 1, it is characterized in that: described pre-heating drier is the inclination furnace wall that is arranged on the burner hearth front end.
